There are only a lot of flue gas denitration. Today, Shandong Baolan small editor introduces the numerical calculation of SCR Flue gas denitration reactor and its connecting flue, mainly focusing on the following aspects, let's learn about it.
 
(1) optimization analysis of SCR Flue gas denitration reactor and its connecting flue
 
This paper analyzes the possible layout of SCR Flue gas denitration reactor and its connecting flue under the existing limited layout, and comprehensively considers other factors such as load, thermal deformation, etc., so as to determine the relative optimal layout.
 
(2) design optimization of guide vane
 
For the above arrangement scheme, the position and shape of the guide vane are set and improved, so that the velocity deviation of the upper surface of the first catalyst layer is less than 10% required by the catalyst.
 
(3) optimization design of ammonia injection grid
 
Because the total amount of ammonia / air mixture is relatively small compared with the flue gas, under the above conditions of meeting the velocity distribution, by adjusting the relative flow of each injection hole of the ammonia injection grid, the standard deviation requirements of NH 3 / NOx molar ratio on the top surface of the first catalyst layer can be met under certain conditions, which is generally required to be less than 5%.
 
(4) off design analysis
 
For flue gas denitration project, it is usually required to achieve the set denitration efficiency under 50% - 100% load, so it is very important to analyze the change of speed and ammonia distribution when the load changes. Through the numerical calculation of flow field under the condition of variable load, the arrangement of flue and guide vane can be further optimized, so that the set goal can be achieved under any working condition.
 
The above is the calculation related content of SCR Flue gas denitration reactor and its connecting flue introduced by the small editor. I hope it can help you.
